Hallam's Greek

Byron, in his English Bards, etc., speaks of “classic
Hallam, much renowned for Greek,” referring to “Hallam's severe
critique on Payne Knight's Taste, in which were some Greek
verses most mercilessly lashed. The verses, however, turned out to be a
quotation from Pindar.”

It appears that Dr. Allen, not Hallam, was the luckless critic. (See CrabbRobinson: Diary, i. 277.)
